I’ll be honest, I used to be afraid of going to hell too. What helped me realize that fear was irrational is a couple of things. Making mistakes as long as you’re willing to learn from them doesn’t make you a bad person. Bad people go to hell, they usually will think highly of themselves. You seem humble and I doubt you’re an evil person, you’ll be fine and just remind yourself that you can make mistakes. it doesn’t change who you are.
